    <p>Raspberry Pi output node. Can be used in Digital, PWM or Servo modes.
    <p>Digital mode expects a <code>msg.payload</code> with either a 0 or 1 (or true or false),
    and will set the selected physical pin high or low depending on the value passed in.</p>
    <p>The initial value of the pin at deploy time can also be set to 0 or 1.</p>
    <p>When using PWM mode - expects an input value of a number 0 - 100. It can be floating point.</p>
    <p>PWM mode can be used to drive a servo using input values between 10 and 20 only.
